Abilities/Groundbreaker

Groundbreaker fills your Special slot. Melee special ability of the physical school. Base damage 120. Cast 24 ticks, cooldown 130 ticks. Reach 7, arc 55°, up to 12 targets.

You get it by equipping 19 bases across 6 lines: Bearbrand Greatsword, Cragfall Greatsword, Nightglacier Greatsword, Oathbound Greatsword and Sunforge Greatsword and 1 more.

The draft can bend it 6 ways — Echo, Reach, Area, Force, Duration and Critical — and cards that ask for area, critical, on_hit and push will find it.

Between rooms it can be offered 193 cards: 64 written for it specifically, plus the 129 that any ability can take. Those cards can put Burn, Chill and Crumble on it, and attune it to Fire, Frost and Stone.

2 Uniques are built on gear that hands it to you: The Felled Oak and Vowsplitter.
